the Window Server is pretty much hoarked.
You have too many cached NSImages. Because NSImage uses windows to
cache images, and because these windows are a system wide resource
managed by the Window Server, eventually it can no longer create new
windows in any process. The work around is to use Core Graphics
directly, which doesn't suffer from this problem.
My initial reaction to this is that Apple should change the
implementation of NSImage to not use system-wide resources to cache
the images. Is that not a feasible long-term solution (by long-term, I
mean, longer than Michael needs, but say, in a 10.6 dot release)?
